Solomon Islands Tsunami (4/1/2007)

Third bulletin April 6:00pm:
The latest reports (United Nations Office for the Coordination of Humanitarian Affairs; OCHA) raised the death toll to at least a dozen with several missing. This number is expected to rise. An initial 2,000 people have also been reported homeless.

Second bulletin April 2, 2007, 9:00am:
CNN reports that at least 12 people have died in the Solomon Islands tsunami. Most of the damage and inundation has been reported around Gizo about 250km west of Honiara. The Nusature airfield in Gizo is closed due to damage until further notice. The most recent estimates for the earthquake size is magnitude 8.0 at an epicentral depth of less than 10km. Cooktown, Australia was evacuated, but there are no reports of any tsunami. It appears that as with the 28 March 2005 Sumatran event, the presence of islands muted the size of the tsunami. The Tsunami Research Center is continuing to monitor the event, and there will be no further bulletins unless there are new developments.

First bulletin April 1, 2007, 9:00pm:
A powerful earthquake of magnitude at least 7.6 (8.1 by some estimates) struck the south Pacific, within 345 km WNW of the Honiara and only 40 km SSE of the Gizo. A tsunami was generated and has already been captured by tide gauges – it was about 21 cm at Honiara. The main energy lobe is directed south east, towards Australia. However, the Solomon Islands chain may disperse the energy rapidly. The main impact is expected in the Solomon Islands, and communications are down.

The Tsunami Research Center is monitoring this event and will periodically update the site. For immediate information, call Mr. Burak Uslu 213 422 2290, or Dr. Aggeliki Barberopoulou at 213 740 5129.
